A Moxa IoT Gateway is a rugged industrial device that connects legacy equipment and sensors to cloud platforms or SCADA systems, enabling Industrial IoT (IIoT) and remote monitoring. It acts as a bridge between OT (Operational Technology) and IT (Information Technology), helping industries like manufacturing, energy, and transportation digitalize and automate operations. 🧠 Key Functions Function Description Protocol Conversion Converts protocols like Modbus, OPC UA, MQTT, etc., to communicate between field devices and cloud. Edge Computing Can process and filter data at the edge before sending it to reduce bandwidth and latency. Secure Remote Access Enables safe remote device monitoring/configuration. Data Logging Collects and stores data locally if the network goes down. Cloud Connectivity Supports Azure, AWS, Alibaba Cloud, etc. 🔧 Key Features of Moxa IoT Gateways Feature Description Industrial-Grade Design Withstands wide temperature ranges (-40°C to +75°C), vibration, and harsh environments. Multiple Interfaces Serial (RS-232/422/485), Ethernet, Digital I/O, USB, CAN, etc. Wireless Options Wi-Fi, LTE/4G, NB-IoT supported on some models. Preinstalled Software Some come with ThingsPro Suite (for Modbus to MQTT/REST conversion, cloud integration). Security Includes firewall, VPN, secure boot, and device authentication. DIN-Rail / Wall Mountable Easy to install in cabinets or control panels. 📦 Common Moxa IoT Gateway Series 1. UC Series – Arm-Based Computers/Gateways Lightweight, low-power gateways with Linux-based OS. UC-2100/UC-3100/UC-5100: Compact, rugged, edge-computing capable. Features: Serial + LAN, cellular modems, SD card support. OS: Debian, Yocto Linux. 2. ThingsPro Gateway A software suite used on UC gateways. Simplifies Modbus polling, MQTT publishing, RESTful API integration. Cloud-ready (AWS, Azure, Alibaba). 3. MC Series – x86-Based Industrial Computers Higher performance than UC series. Used for complex edge analytics or multiple protocol bridging. Example: MC-1100, MC-3201 ☁️ Cloud & Protocol Support Protocol Use Modbus TCP/RTU Most common legacy industrial protocol.
